the element of surprise in design is what makes a room something special ~ something that makes you go "ahhh" when you walk in. without having magic tricks & fully automated lights, walls, & windows in a room, you can still give that subtle hint of surprise by adding a small splash of color to an otherwise monochromatic room. the concept is to have a space that is soothing (the monochrome) and stimulating (the color splash). can you feel it?
p.s. can you tell which one was done in the 1960's?
